Recently, we've compiled lists of 40 Female Filmmakers to Follow on Twitter and 100 Filmmakers to Follow on Twitter, but we felt it was time to highlight some of our favorite documentary filmmakers on Twitter. It's an eclectic and impressive group responsible for some of our favorite documentaries, including, most recently, "Stories We Tell," "The Armstrong Lie," "Valentine Road," "The Act of Killing" and "The Punk Singer."

Note that this isn't a comprehensive list, but that all of these filmmakers are active on Twitter -- and whether they're promoting their own projects or debating the merits of various documentary techniques, these cinematic rabble-rousers are consistently informative, entertaining and engaging.
